Big weekend clean-up?

This morning I went upstairs to get a short sleeved blouse out of one of the closets (my winter storage). It is still too cool here to wear short sleeves everyday and the weather report for the Memorial Day Weekend is cool and rainy - maybe even some snow. As I looked around upstairs, I thought, "Hey, I think I can tackle a room over the 3-day weekend." Then I remembered that we are going to our nephew's high school graduation party Saturday, the actual graduation on Sunday, and then a family BBQ on Monday. I was bummed when I realized it, but then I made a plan to do a little each day. I won't be as productive as if I take an entire day to dedicate to the project, but at least I'll get started on it. It can get pretty hot up there in July and August, so it's best to start now!
I guess tomorrow I'll take some "before" pictures. I hate doing that because, A) it's kind of embarrassing to have it documented and B) it makes me feel that I actually have to do something about it. I know it's ridiculous, because the "under-stairs room" was the worst, most cluttered part of the house. I think the reason it's disturbing to me is because even I can't believe that we have SO MUCH STUFF!
